I was thinking of a standard OS package repository, e.g. Yum or APT, and
a link to that from the ELPA package.

Rgeardless, maybe an ELPA package should be able to declare its
dependency on specific OS packages. This could be useful even if the
package doesn't have binaries or modules.

Help me understand. Say user installs module FOO-1 which binds to
library BAR-1. User upgrades BAR-1 to BAR-2 or uninstalls BAR-1. What

What happens to users that don't have a compiler? Do you think OS
distributions will pick up the module distribution piece like they did
with Python, Perl, etc.?
